Red sky at night, shepherd's delight. Red sky in the morning, shepherd's warning

The shepherd moon (2 a) of the second planet has a red sky from its thin argon atmosphere above 5km altitude. While the old saying had some relevance on Earth, in this instance the warning is of the impending collision with its sister moon.

Below 5km the sky appears blue and with the red only appearing as you look up.

The system hosts the first collision ever observed between a landable atmospheric planet and another body.

The moons collide infrequently, with a synodic period of just over 220 days, and may occasionally narrowly miss each other as they pass.

Body 2 a also has water ice volcanism, and three biological species can be found on it:

Bacterium Verrata - Blue (3,897,000 Cr)
Fonticulua Campestris - Amethyst (1,000,000 Cr)
Fumerola Aquatis - Orange (6,284,600 Cr)

The first collision was on the Jun 12th 2023 at 13:44 UTC, and lasted nearly 24 hours.
